# Chippewa Valley Regional Airport

Chippewa Valley Regional Airport (IATA: EAU, ICAO: KEAU, FAA LID: EAU) is a public use airport in Chippewa County, Wisconsin, United States. The airport is owned by Eau Claire county and is located 3 nautical miles (5.6 km; 3.5 mi) north of the central business district of the city of Eau Claire, Wisconsin.
It is the largest airport in the 30-county northern Wisconsin area and serves primarily the Chippewa Valley region, operating on a budget approved by a commission equally representing the interests of Chippewa, Dunn and Eau Claire counties.
The airport is mainly used for general aviation and business travel; the Eau Claire-based Menards corporation uses CVRA to base their fleet of aircraft to serve their stores throughout the Midwest. It is occasionally used as an alternative landing site for flights bound for Minneapolis-Saint Paul International Airport. As of December 2022, only one commercial airline, Sun Country Airlines, provides service for CVRA to Minneapolis International. In December 2024, United Airlines announced the start of regional service to its hub at Chicago O'Hare.
The airport is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2025–2029, in which it is categorized as a non-hub primary commercial service facility. It is the eighth busiest of eight commercial airports in Wisconsin in terms of passengers served.

## History

In 1923, 80 acres (320,000 m$^2$) of land in Putnam Heights were purchased to build an airport. In 1929, Eau Claire Airways was started at the airport, offering training and scheduled taxi service to destinations in Wisconsin and Minnesota.
In 1939, work on a new airport started north of Eau Claire. In 1940, Eau Claire County Airport started operations at its current site. Eau Claire Municipal Airport opened in 1945, while Chippewa Valley Regional Airport was officially opened in 1947 with the arrival of a Northwest Airlines DC-3. At this time, Eau Claire had three airports. Upgrades at Chippewa Valley Regional Airport were made in further decades, with a terminal addition in 1981. Another terminal remodeling and expansion was completed in 2009.
A new $3.9 million 65 feet (20 m) control tower was built in 2005 and opened in November 2006. Passenger loading used to be from the ramp until a jetbridge was installed in the spring of 2011.
In 2015, the Airport Commission Room was renamed the Duax Commission Room after long-time airport supporter and former airport commissioner David Duax.
In July 2024, the airport board voted to support the return of SkyWest Airlines despite the community's overwhelming support for keeping the incumbent carrier, Sun Country Airlines. Sun Country's bid would have continued service to four nonstop destinations from Eau Claire in contrast to SkyWest's one city, Chicago. Sun Country posted the highest number of enplanements seen at the airport in the last 15 years in 2023.
SkyWest previously served the airport as an Essential Air Service provider until November 2022, before choosing to leave the market. The Essential Air Service bid was approved by the Department of Transportation, SkyWest resumed with flights to O'Hare International Airport on December 13, 2024.
